CFG all whom, it may concern;

Be it known that I, GEORGE A. SMITH, a citizen of the United States, residing atChicago, in the county of Cook and State of Illinois, haveinvented a certain'new and useful Improvement in Wheel-Rims for ElasticV Tires, of which the following is a specification.

YVhere a wooden Wheel rim or felly is provided with a metal felly band or rim adaptedA to provide an annular seat for an elastic tire the wooden felly will at times have atendency to expand as the result ofy exposure to water-as, for example, when used in rainy weather. As the metal restraining rim or bandprevents expansion in an out-ward diametric line, the expansion toward other available sides of the fellywill tend to contract or compact the wood at points and in such al readily applied and llocked upon wheels.y

' other useful ends, the perimeter of thewooden, felly is beveled at opposite sides of a longifscrews or bolts, and in the event of shrinkvTo the attainment of the foregoing and tudinalcenterline, so as `to form annular beveled seats for a rirn comprising a couple of metal clamp-rings adapted when in place to conjointly form a suitable retaining-channel for the base portion of an elastic tire. These rings are adj ustably tied together by age of the wood they canbe adjusted with reference-to such shrinkage. Said rings can also be detached', so' asfto permit the tire to be applied or put on as desired. I

In the aoc'ompanying drawings, Figurel is a section taken transversely through a tire, felly, and sectional tire-holding metal' rim composed of two rings or annular sections. Fig.2 is a like view with the tire omitted. Fig. 3 is a` section on line .fr in Fig. 2.

The elastic tire Amay be of the pneumatic, cushion, or solid'type. g

The wooden felly B is understood'to be annular, as usual, and is double-beveled along ytogether by the bolts.

its perimeter-that is to say, it` has two bev-y eled face or peripheral portions i) b, respectively opposite a line extending centrally and longitudinally along its perimeter.

The metal felly band or rim G is sectional, being composed of a pair of annular sections or rings c c, having their annular inner sides beveled to fit the bevel-face portions of the wooden rim or felly. The outer or peripheral sides or faces of these rings or sections are transversely concaved or recessed, so that when in placeupon the felly said rings or sections will provide an annular channel in which the base portion of an elastic tire can be seated and held. The rings or' sections are adjustablytied together by screws or bolts D, a preferred arrangement being to transversely bore the rings or sections for bolts having threaded ends for tighteningnuts d and towcountersink the sides of the rings or sections, so as to provide recesses in which the headsof the bolts and the tightening-nuts can be recessed, as illustrated. The rings or annular sections are primarily arranged with a small space between them,

whereby in the event of shrinkage on the part of the wooden -felly the rings or sections can be adj ustedthe one towardjthe other.

To apply the tire, iu case it is not sufficiently elastic to permit it to be convenientlystretched and sprung` upon the metal rim one section of such metal rim can be detached, and after placing the tire in proper lposition the section thus removed can be again applied, andthe two sections can then be tied By'tightening up the nuts the rings or sections can be drawn together and rmly clamped upon the folly, and should the latter shrink the nuts can be further tightened up, so as to again cause the sections to firmly bind upon their seats. What I claim as my invention is-,

l. A wooden fellyhavingits perimeter beveled yat `each side of a centerline, and a channeled metal rim comprising avcouple of rings or annular sections fitted to seat upon the beveled portions of the felly' and'adapted when in place thereon to conjointly form an annuheld upon the fell y by bolts or screws.

'I Oo 2. A Wooden felly havingits perimeter beveled at eaell side ofa center line, and a ehannelod met-al rim comprising a couple of rings or sections adjustably drawn lche one toward the other and elampedfupon the felly by bolts and tightening-nuts; the inner sides of the rings orseetions being beveled in conformity with and fitted to the beveled portions of the f felly, and having their outer sides adapted to eonjoinbly provide a channel for receiving the base portion oi' an elastic tire, and said rings orseetions being primarily applied with an intervening space.

3. The combination of a Wooden felly havin g annular beveled peripheral seats respectively at opposite sides of a center line; ay sectional meta-l rim providing an annular .channel and composed of a couple of rings or annular sections having inner beveled sides fitted to the bevels of' the wooden felly; tie-, 2o

bolts and nuts whereby elle rings or annular sections are adjust-ably clamped upon the wooden folly; and an elast-ie tire having its base portion held Within the annular enannel of the sectional metal rim.
